I had  blisters on two toes, from walking at zoo. Skin was broken badly and 
it looked like one  toe had a hole in it, as blister had broken and skin was 
raw and very  red and bleeding slightly. The following day I could not put a 
shoe on.   I soaked a piece of sterile cotton with CS and put it on the blister 
and put a bandage lightly around that and went to bed that way. Got up in 
morning, cleaned area and reapplied CS.  Had to do this for two days while 
wearing 
flip flops, third day the area was normal color, hole area closed. I kept on 
for another day and I was fine.
